FUEL MIXER.

Application filed May 16,

This invention relates to automobile accessories and morG'particularlyto afuel mixer adapted to be mounted adjacent the junction of acarburetor and intake manifold so that a charge passing from thecarburetor through the manifold will be acted upon by the mixer and freegasoline in the charge broken up.

One object of the invention is to provide amixer including awheel'adapted to be rotated by the charge passing through the manifoldand having blades which will very effectively break up free gasoline inthe charge and cause it to be thoroughly vaporized.

Another object of theinvention is to provide an improved type ofmounting for the wheel and so form the mounting that air may passinwardly between bearing arms between which the wheel rotates andthereby become thoroughly mixed with the charge of combustible fluidpassing from the carbureter through the manifold.

Another object of the invention isto provide. a deviceof this characterwhich may be easily installed and firmly held in proper position when inuse.

The invention is illustrated in the accompanying drawing, wherein igure1 is a view showing a carburetor and a portion of a manifold partiallyin sec tion with the improved mixer applied thereto;

Fig. 2 is a sectional view taken on. the line 22 of 1;

F is a perspective view of a gaket forming a carrier for a modified formof mixer;

F 4 is a transver e sectional view through the gasket with the modifiedform of mixer applied thereto;

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 3, and V Fig. 6is a perspective View of a mounting orming a portion of the mixer shownin ig. l. 7

The vaporizer shown in Figs. 1 and 2 is intended to be mounted in themanifold 1 V adjacent the end thereof which is connected with thecarburetor 2 and in order to mount the vaporizer an opening 3 is drilledor otherwise formed in the manifold, as shown in Fig. 1. The mounting atwhich forms a portion of the vaporizer is provid d with bearing arms 5which extend from a base 1927. Serial N0. 190,297.

6 and rotatably support a mixing wheel 7, the blades 8 of which'areformed with longitudinally extending slots 8'. This wheel is disposedtransversely in the manifold and is rapidly rotated by the charge suckedfrom the carburetor through the manifold. A portion of the charge passesthrough the slots in the blades and, therefore, free gasoline containedin the charge will be acted upon and very thoroughly broken up. Anopening is formed in the base 6 of the mounting and carries a threadedtubular stem 9 which projects into the opening 3 formed in the wall ofthe manifold and engages in the threaded end portion of the bore 10formed axially through the fastener or carrier 11. By referring toFig.1, it will be seen that the inner end portion of the carrier is reduced to form a neck 12 which fits snugly in the opening 3 and is of adepth corresponding to the thickness of the manifold wall. Therefore,the fastener 1 ay be tightened to firmly retain the mounting in placewith the wheel extending transversely in the manifold. A hollow valveseat. 13 is screwed into a threaded outer end portion of the bore 10 andforms a seat for a valve ball lat which is yieldably held upon the seatby a spring 15 confined between the valve ball and end of the stem 9. Bythis arrangement the bore will be normally closed by the valve ball butwhen a suction takes place through the manifold from the carburetor to acylinder of an engine the valve ball will be drawn away from the seatand air may be sucked into the manifold. This air passes inwardlybetween the arms 5 of the mounting and since the blades of the mixingwheel pass across the inner end of the tubular stem the charge of airwill be acted upon by the blades of the rotating wheel and mixed withthe charge passing from the carbureter. Therefore, a very explosivecharge will be fed to the engine. By adjusting the valve seat thetension of the spring may be controlled and the quantity of air whichpasses inwardly with each suction regulated.

In Figs. 3, 4;, 5 and (3, there has been shown a modified form ofvaporizer which includes a gasket 16 adapted to be secured between thecarbureter and intake manifold and having a passage 17 which registerswith the bore of the manifold and outlet of the carburetor. An opening18 is formed through the gasket, as shown in Fig. 5, and the side facesof the gasket are formed'with grooves constituting seats-19 adaptedtoireceive the base portions 20 of'arms 21 corresponding to the arms 5.Screws 22 may be employed t retain the arms in place or a small boltsubstituted therefor if so desired. The bearing arms 21 extend radiallyof the opening or passage 17 and rotatably mount a mixing wheel 23 whichcorresponds, to the' wheel 7 and is provided with slotted blades 24:- Ahollow valve seat 25 is screwed into the outer end portion otthe opening18 and within the opening 18' is placed a valve ball 26 engaged by aspring 2'? which yieldably retains the valve ball against the seat sothat air maybe sucked inwardly but cannot pass outwardly through theopening. 7 The operation is the same as the form of mixer shown in Figs.1' and 2, the only dilference being that the mounting arms for the wheelare engaged with a carrier secured between the'earbureter and manifoldinstead of being held in place byla carrier passed through an openingformed inthe wall of the manifold and the valve controlledair inlet isnot disposed between the arms.

v tween thus described the invention, I

threaded stem adapted to fit into an opening formed inthe wall of amanifold, bearing arms extending from said base, said base being formedwith an air passage between said arms extending axially through the stema mixing wheel rotatably mounted besaid arms, fastener formed with athreaded bore and having a reduced end to be fitted int'o the opening inthe manifold and screwed upon said stem to secure the mounting in themanifolchthe outer end portion'of the fastenerbeing adapted to bearagainst the outerface ol the manifold, a tubular valve seat screwed intothe outer end portion of said bore, a valve ball in the bore to seatagainst the. inner en'd of said valve seat and a spring in said borebetween said ball and stem ,yieldably holding the valve ball inengagement with itsseat.

In testimony whereof I aflix my signature.
